Definitions

• the invention relates to a device for preparing a beverage from a substance contained in a capsule with a circumferential collar by means of a liquid according to the preamble of claim 1.
• Such devices are used for some time, for example for the production of coffee or tea.
• the capsules it can involve to rela ⁇ tively rigid, cup-like containers for example, synthetic ⁇ -material, aluminum of a laminate. Conceivable, however, are other forms of individual packaging with a circumferential collar such as flat pads.
• Comparable capsules have become known, for example, from EP 1 500 357 or EP 1 944 248.
• the capsules have a base body with a preferably rotationally symmetrical receiving cup and a subsequent, flange-like collar.
• the receiving cup is sealed for hermetic packaging of the packaged product with a film which is welded to the collar, for example, or otherwise attached depending on the material.
• EP 1 757 212 or WO 2008/004116 discloses devices in which the capsule is held by means of a positioning unit in an intermediate position between the two chamber parts before they are closed for the brewing process.
• the lateral guide sections are spread apart during the closing movement, so that the two chamber parts can be pressed sealingly against each other.
• the capsule falls downwards under the action of gravity without the positioning unit impairing the falling movement.
• a considerable disadvantage of these expandable guide sections is that many moving parts are required, which complicate and increase the cost of the construction. Lateral movement also requires space, making lean construction difficult.
• the device is intended to have as few moving parts and yet working at ⁇ reliably.
• the design should allow a slim design and be inexpensive to produce.
• Aussedem should on the peripheral collar of the capsule when liberated from the positioning as possible little or no forces angrei ⁇ fen, since a deformed collar can have a negative impact on the tightness of the brewing chamber. Even the ejection of the used capsule after the brewing process can be difficult with deformed collar.
• the asymmetrical design of the two opposite guide sections as a joint guide on the one hand and as Freistel ⁇ ment guide with a recess on the other hand allows in the simplest way a freeing of the capsule from the positioning without laterally movable parts and virtually no appreciable force ⁇ exercise on the circumferential collar.
• the capsule held loosely in the positioning unit makes a serpentine movement when the chamber parts are closed as a result of being acted upon by one of the chamber parts, which can be subdivided essentially into two phases of movement.
• a first phase of movement the capsule is rotated from the intermediate position slightly around the joint guide and thereby released from the exemption guidance.
• the capsule turns to a specific Angle at an angle to the closing direction or to the vertical insertion plane.
• the capsule performs a la ⁇ terale movement, wherein it is also freed from the joint guide and in turn is placed with its longitudinal axis approximately parallel to the direction of movement of the chamber parts back.
• the joint guide is designed so that it allows rotation or tilting of the capsule by an angle of 0 ° degrees to 45 ° degrees from the vertical insertion level. As a rule, however, a rotation of less than 15 ° degrees is sufficient.
• the joint guide can thereby make this rotational movement possible in that, at least in the region of the intermediate position, it has an approximately V-shaped or approximately U-shaped guide groove .
• a Kippge ⁇ steering is formed with a smaller or larger tilt angle.
• the guide groove in the region of the intermediate position could also have a flexible wall section, so that the guide groove can be widened for rotating or tilting the capsule.
• the two guide portions are preferably formed so that they form at its lower end a support for the collar for holding the capsule in the intermediate position. It would also be conceivable for the support of the capsule is carried out in the intermediate position a separate element which is not allocated to the Füh ⁇ approximately sections.
• one of the chamber parts is fixedly arranged on a frame ⁇ , wherein the other chamber part is slidably mounted in the frame.
• both chamber parts are movably mounted and that they move towards each other to reach the closed position.

• the dimensioning of capsule holder and positioning unit is preferably chosen so that the two guide sections are slidable on both sides over the capsule holder when closing the cavity. In this way, the capsule can be particularly advantageous deposit in the cavity before the two chamber parts are pressed sealingly against each other.

This advantageously has a ramp surface inclined to the introduction plane and a return surface located approximately in the introduction plane. The ramp surface is used to slightly lift the capsule while freeing the capsule from the edge exemption guide, so that the return surface adapted to engage the capsular rim during the ⁇ réellesbewe ⁇ supply.
• the joint guide has a guide ramp, which it forces when freeing the capsule from the articulation guide in the second movement phase, a lateral movement of the capsule ⁇ .
• This ensures that the capsule collar does not remain in the guide groove of the joint guide, but is laterally pushed away by the guide ramp.
• the capsule reaches its normal position again, relative to the two Kammertei ⁇ len.
• the lateral movement can be further promoted by the fact that the release guide has a bevel in the region of the recess. This bevel prevents the cap ⁇ selkragen abuts in the lateral return movement of the exemption guide.
• the loading of the capsule to trigger the serpentine movement and thus to be released from the positioning unit by one of the chamber parts can also be a Ele ⁇ ment, which is associated with only one of the chamber parts.
• Particularly advantageous is the application of a compressible spring, which favors the ejection of the capsule from the cavity at the same time. This has that a pressure is additionally the advantage upon impact of the spring on the capsule gradually built up until finally the Sch Siemensbe ⁇ movement is triggered. This further reduces the risk ei ⁇ ner damage to the capsule.
